New CT scanner offers more detailed images, faster scans

Aging equipment replaced with state-of-the-art diagnostic tools

RED DEER — Patients are now benefiting from a new state-of-the-art computed tomography (CT) scanner at the Red Deer Regional Hospital Centre (RDRHC).

CT scanners are critical diagnostic tools that enhance the ability to screen for and more accurately diagnose medical conditions such as internal bleeding, lung disorders and cancer. The new scanner, which went into operation last week, delivers high-quality images using the most current technology.

“We are so pleased that people in Red Deer and the surrounding communities now have access to a new CT scanner, plus cutting-edge equipment that will provide fast, safe, quality diagnoses,” says Sarah Hoffman, Alberta’s Minister of Health. “This will ultimately improve patient care and ensure people in central Alberta get the right treatment at the right place and at the right time.”

“We’re very excited about this,” adds Leane Young, the hospital’s manager of Diagnostic Imaging. “This new scanner replaces one that was 12 years old and provides us with quicker scan times, more advanced imaging and a number of different features that we’ll be able to use.”

One of the features offered by the new scanner is an application that allows for enhanced image clarity in patients with metal prosthetics. Metal objects, such as orthopedic implants, can create dark streaks across images that can hinder visualization of medical conditions.

The enhanced image quality is another key benefit. The new CT is a 128-slice scanner, as opposed to the 64-slice machine it replaced. CT scanners take pictures of slices of the body, which are then stitched together electronically to reveal detailed images.

“The stellar detector on this new scanner is state of the art. It is the next generation of detector technology,” Young says. “The level of detail we’re able to capture produces amazingly clear, crisp images for our radiologists to interpret.”

Red Deer Regional Hospital Centre operates two CT scanners, completing an average of 2,000 scans per month. CT scanners provide important diagnostic imaging for a variety of uses, including trauma evaluation, detection of tumors, heart disease, and assistance with surgical planning. Funding for the replacement project included $935,000 in equipment and $600,000 in renovations, provided through an existing Alberta Health Services’ (AHS) capital equipment replacement budget.

In addition to the CT scanner replacement, Diagnostic Imaging is also currently replacing one of the hospital’s two nuclear medicine cameras. These specialized cameras are used to detect small amounts of radioactive materials, known as radiotracers.

Radiotracers, which are typically injected into the bloodstream, travel through the area of body being examined and give off energy in the form of gamma rays. The gamma rays are detected by the specialized camera equipment and a computer to create images.

“The technology behind this equipment gives us the ability to combine nuclear medicine images with CT images, which allows for precise identification of any abnormality on the image,” says Young. “The fusion capabilities function to localize abnormalities in the heart and bones, localize tumors and evaluate infection sites.”

Expected to take 10 weeks to complete, the $1.45-million nuclear medicine camera project includes new equipment as well as the cost of renovations to accommodate the equipment and revitalize the imaging suite.

To help meet ongoing need for such procedures during the replacement project, Diagnostic Imaging is extending the hours of operation for nuclear medicine.

“It is important that we keep up with changes in medical technology and having this new equipment is a great benefit to patient care and the diagnostic imaging services offered to our patients,” she says.

Alberta Health Services is the provincial health authority responsible for planning and delivering health supports and services for more than four million adults and children living in Alberta. Its mission is to provide a patient-focused, quality health system that is accessible and sustainable for all Albertans. .
